For achieving the above object, the utility model proposes the pneumatic operation of landing gear of a kind of unmanned plane, comprise wheel, first connecting rod, second connecting rod, third connecting rod, cylinder, valve, servomotor, the suction quantity of described valve control cylinder, the motion of described Serve Motor Control cylinder, described second connecting rod is connected with third connecting rod is movable, and described cylinder is connected with first connecting rod is movable, cylinder is connected with second connecting rod is movable, and described wheel is connected with first connecting rod is movable.
As preferably, described third connecting rod is provided with the 3rd guide pillar, and the 3rd guide pillar is connected with second connecting rod is movable.
As preferably, described first connecting rod is provided with linkage section, support end and the first guide pillar, linkage section is provided with the second guide pillar, and the second guide pillar is connected with second connecting rod is movable, and the second guide pillar is connected with cylinder is movable, and the first guide pillar is connected with first connecting rod is movable.
As preferably, described second connecting rod offers stroke groove, and the width of stroke groove equals the diameter of the second guide pillar, and the length of stroke groove is greater than the length of coupling end.
As preferably, described third connecting rod is provided with projection, and projection is fixedly connected with third connecting rod, projection has the first inclined-plane.
As preferably, described first connecting rod is provided with the second inclined-plane, and the second inclined-plane and the first inclined-plane fit.
The beneficial effects of the utility model: the utility model, by will the alighting gear of unmanned plane be made by cylinder action, uses simple bar linkage structure to complete the folding and unfolding action of alighting gear when unmanned plane takes off and lands.Alleviate total quality and the volume of the equipment of rising and falling, simultaneously also to a certain extent reduce equipment cost.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
